Kickback and corresponding
precautions
Kickback is the sudden reaction from a
chopping or blocked grinder attachment
such as a grinding disc, grinding plate,
wire brush etc. Chopping or blocking leads
to sudden stopping of the rotating attach-
ment. This causes an uncontrolled electric
tool to accelerate in a direction counter to
the rotational direction of the attachment
tool. If, for example, a grinding disc cuts
into the workpiece or blocks it, the edge of
the grinding disc that digs into the work-
piece can get caught and, through that,
break off the grinding disc or cause a kick-
back. The grinding disc then moves towards
or away from the operator, depending on
the direction of rotation of the disc at the
blocked spot. Here, the grinding discs can
also break. A kickback is caused by wrong-
ly or incorrectly operating the electric tool.
It can be avoided by suitable cautionary
measures, such as described below.
a) Hold the electric tool very firmly and
bring your body and your arm into a
position in which you can resist the kick-
back force. Always use the supplemental
handle if available to give you the best
control over kickback force or reaction
time during acceleration. The operator
can master the kickback and reaction
force through suitable precautions.
b) Never bring your hands near a rotating
attachment tool. The attachment tool
can run over your hand in the kickback.
c) Keep your body away from the area
in which the electric tool would move
during a kickback. The kickback drives
the electric tool in the counter-direction
to the rotation of the grinding disc at
the blocked spot.
d) Work particularly cautiously in corner
areas or where there are sharp cor-
ners etc. Prevent the attachment tools
from recoiling from the workpiece and
jamming. The rotating attachment tool
tends to jam when near corners, sharp
edges or when it recoils from such. This
causes a loss of control or kickback.
e) Do not use chain or toothed saw bla-
des. Such attachment tools frequently
cause a kickback or loss of control over
the electric tool.
Special safety instructions for
grinding and cutting
a) Use only grinders which have been
approved for your electric tool and the
protective hood intended for these grin-
ders. Grinders which are not intended
for the electric tool may not be suffici
-
ently shielded and are unsafe.
b) Depressed Center grinding wheels must
be pre-assembled so that their surface
not above the level of the edge of the
guard stands out. An improperly moun-
ted grinding wheel, which extends bey-
ond the level of the edge of the guard,
not sufficiently shielded.
c) The protective hood must be securely
attached to the electric tool and adjus-
ted so that the greatest level of safety
is reached, i.e., the smallest possible
amount of the grinder is exposed to the
operator. The protective hood should
protect the operator from broken bits
and accidental contact with the grinder.
